This invention relates toimprovements in matrix-setting and type-lihe-casting machines in which by striking'keys arranged on a keyboard the matrices situated in a magazine are released by'means of any de sired transmission members, and consists in the fact that thelteyboard to be operated by w anda )articularl reatdisadvanta e is the fact that, due to the keyboard. being rigidly attached at a definite height, the compositor is either compelled to operate the machine whilst standing up during the Whole of the working period, or sitting in a most uncomfortable fashion. If, due to special seating arrangements, he is actually able to operate the keys comfortably, it is generally not so easy for him to see the line set or to operate the other levers and adjusting devices of the machine. Heretofore, this has been remedied by many different kinds of specially constructed adjustable seating arrangements orthe machine has been built with a very low keyboard which is therefore only suitable for working while sitting. None of these devices, however, is able to give satisfaction, because the physical constitutions of the compositors working at the same machine often even in alternate shifts are as varied as their customs. There has been for some time therefore a need for the provision of devices which will enable any compositor to work alternately sitting or standing as desired at certain periods in order to avoid fatigue while retaining all the advantages and conveniences in the operation of the machine.

It is the object of the invention to eliminate the disadvantages which have been experienced in professional circles up to most recent times on account of the absence of suitable devices. This is attained by a vertically adjustable arrangement of the keyboard enabling the compositor to adjust the height of the keyboard'in accordance with the conditions which he has found to be most A favourable for his comfort, and also in accordance with his custom, so that with the equal advantages he can alternate as desired between the sitting and standing method of working. Onaccount of this reduction in the possibility of fatigue of the compositor his efficiency is of course increased and according to the invention the arrangement is such that the vertical adjustment of the keyboard.

form of the invention, and

Fig. 2 is a diagrammatieview of a slightly modified form thereof.

The keyboard 1 shown in a lower and upper position is slidably'secured by means of a guide bracket 3 to a guide bar 2 on the ma chine frame. The said guide bracket 3 fits for eX ample-bymeans of a dovetailguide overcorresponding guide-ways on the bar 2 as at 3. A nut 4 mounted on a screw-thread ed spindle 5 ournalled in the machine frame is rigidly secured to the guide bracket 3. A bevel Wheel 6 having its teeth meshing with those of a bevel Wheel 7 is fixed to the upper end of the screw-threaded spindle 5. The bevel wheel 7 is fast on a shaft 8 which is likewise journalled in the upper part of the guide bar 2 on the machine frame and which has a handle 9 mounted fast ordetachably ment in a vertical direction along the screwthreaded spindle 5. The nut 4, however, is so connected to the bracket 3 that, during its movement along the screw-threaded spindle.

5, it always carries the bracket 3, and consequently the keyboard 1 rigidly secured to said bracket, either'upwardly or downardly.

The vertical adjustability of the keyboard 1 may, however, be attained by any and 6,

other means, without departing from the scope of the invention.

In order not to complicate the construction of the setting machine, despite this vertically adjustable arrangement of the keyboard, it is preferable, for example, in matrix-setting and type-line-casting machines with matrices guided on Wires, to employ instead of the wires, link levers, rollers and the like which have been employedheretofore for connecting the striking keys 10 to the matrix release devices other motion-transmitting means 11. In the form shown in Fig. 1 the keys 10 are connectedby electrical contacts and leads 11 to electromagnetic re lease devices 12 which are situated in front of the magazine for rel-easing the matrices 13 suspended from their-guide wires 14.

In the arrangement shown in Fig. 2 "Bowdeif cables 11 extend from the keys 10 to the release devices 12 which are situated in front of the magazine and are for controlling the matrices l3 suspend-ed from their guide wires 14.

By means of a vertically adjustable key-- board the above-mentioneddisadvantages inherent to the fixed. keyboard are accordingly eliminated in a simple .manner.

Having thus fullyzdescribed the invention What is claimed and desired to be secured by Letters Patent is 1. A matrix-setting and type-line-casting machine of the type in' which the matrices situated in a magazine are released. by striking keys arranged on a keyboard and flexibly connected to the matrix release devices on the magazine, means for slidably mounting the keyboard for vertical movement, and means for adjusting the keyboard to the desired position of height.

2. A matrix-setting and type-line-casting machine including in combination a matrix magazine, matrix release devices in front of the magazine, a composing keyboard, keys on the board, means for adjustably mounting the keyboard, means for maintaining the keyboard in the desired position of adjustment, and flexible connections operably connecting the keys and matrix release devic 3. A matrix-setting and type-line-casting machine as claimed in claim 2, wherein the ,a nut mounted in the'bracket and having its screw-thread engaging the screw-thread of the spindle. f I

4;. A matrix-setting and typeline-casting machine as claimed in claim 2, wherein the means for adjustably mounting the keyboard includes a rotatably mounted screwthreaded spindle, a bracket on the keyboard operably engageable with the spindle so as to be adjusted Vertically upon the. rotation of the spindle and wherein the means for adjusting the bracket includes a rotatable shaft journalled above the spindle, internleshing gear wheels on the shaft and on the spindle, and a handle carried by the shaft for rotating the latter and. consequently the spindle.

5. A matrix-setting and type-line-casting machine as claimed in claim 2, wherein the means for flexibly connecting the keys on the keyboardwith the matrix release devices in clude Bowden cables.

6. A matrix-setting and type-line-casting machine as claimed in claim 2, wherein the matrix release devices are electron'iagnetically controlled and wherein the means for connecting the said devices with the keys include electrical contacts and leads.
